6rd Traffic and Lower IP Address Reputation


I recently switched my router to using OpenWRT, and as part of the upgrade I was able to finally start using IPv6 via my ISP’s 6rd relay (my router’s old firmware didn’t support 6rd). However, since I set that up, I’ve noticed I’m seeing more captcha’s than normal.

I installed Privacy Pass, which helps somewhat, and I’ve reviewed the steps listed here:

But as far as I can tell there’s no reports on Project Honeypot or anywhere else that indicate my IP address (either the IPv4 or IPv6) is bad.

Is it possible the 6rd traffic is being marked as non-residential/datacenter traffic (because it’s going through my ISP’s 6rd relay), and causing a problem with captcha?
